WIRELESS MOBILE COMMUNICATION - A STUDY OF 4G TECHNOLOGY

Abstract

Mobile communication is one of the hottest areas and it is developing extremely fast in present times with advanced techniques emerging in all the fields of mobile and wireless communications. The exponential growth of user demands, the limitations of the Third Generation of Mobile Communication Systems(3G) and the emergence of new mobile broadband technologies on the market have brought researchers to a throughout reflection on the Fourth Generation (4G).The purpose of this paper is to provide an overview of the different
aspects of 4G which includes its features, its proposed architecture , key technological enabler, its benefits over existing wireless communication system, present key challenges and point to some proposed solutions.
